OLIVER H. ARNO, OF \VILMINGTON, ASSIGNOR TO AMERICAN AUTOMATIC ORGANCOMPANY, OF BOSTON, MASSACHUSETTS.

MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 233,721, dated October26, 1880.

" Application filed June 18, 1880. (No model.) Patented in England May26, 1880.

To all whom it may concern Be it known that I, OLIVER H. ARNO, ofWilmington, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Mechanical MusicalInstruments, of which the following is a full, clear, and exactdescription.

This invention pertains to that class of me chanical musical instrumentsarranged by the 1o passage of a perforated paper strip to secure theautomatic playing of the instrument in accordance with the dispositionof the perforated aud unperforated portions of the paper strip inrelation to each other, and to the I 5 mechanism for opening and closingthe reedvalve, &c.

In a patentgranted to me May 18,1880, and numbered 227,714, theperforated strip is provided with two lines of perforations, the

perforations of one line being for opening, and the perforations of theother line being for closing, a sliding valve through the medium of twoseparate levers.

The object of my present invention is to dispense with the line ofperforations for closing the sliding valve, and also to open or closesaid valve by means of a single lever.

The invention consists of a reed-valve arranged to slide to open andclose the reed, and

0 of a lever connected to the valve, and constructed and otherwisearranged and disposed in such relation thereto and to the rows ofperforations in the paper strip which correspond to such reed that inthepassage of 5 the perforated and unperforated portions of theperforated strip by a given point the lever opens the valve at thepassage of each perforated portion, and so keeps it open for the lengthofsuch perforation, and closes the valve at the passage of suchunperforated portion, and so keeps it closed for the length of suchunperfora-ted portion, all substantially as hereinafter described.

In the accompanying plate of drawings my 5 invention is illustrated,Figures 1 and 2 being vertical sections in the line of travel of theperforated strip, the one showing the valve as closed and the other asopened.

In the drawings, A represents a horizontal bed or raceway. Along thisbed and under a cross-block, B, the perforated strip of paper 0 passes,suitable mechanism-such as feedrolls-bei n g employed to secure thecontinuous passage of the paper strip.

The paper strip 0 is provided with a series ofparallel rows ofperforations, and each row runs in the line of travel of the stripthrough the raceway. In line with each row of perforations there is anopening, 0,.iu the raceway, and block B and a horizontal lever, D, belowthe raceway A.

Each horizontal lever D, at its one end, 6, is hung to a fulcrum-pin, a,and near its other end,f, it has on its upper side a wedge-piece,

b, suitably located to enter the opening 0 in the raceway and block inline with it.

E is a bent spring placed below each lever. This spring at one end isfastened to a block, (I, and at the other end it presses upwardlyagainst the under side of its lever.

F is a vertical arm attached to each lever, and at its lower end hingedto a reed-valve, G, arranged to slide horizontally over the face of thereed-chamber H. When this valve is slid in one direction the reed-valveis opened, and when it is slid in the other direction the valve isclosed, and the arrangement of each valve and its lever-connectiondescribed is such that the downward swing of the lever closes, and theupward swing of the lever opens, the valve.

The opening of the valve is against the pressure of the spring, and itsclosing is with such pressure.

As each lever is arranged in the travel of the perforated strip 0through the raceway, it opens its valve and holds it open, when aperforated portion of the paper strip is passiug by its wedge-piece b,and it closes its valve and holds it closed when an unperforated por- 0tion of the paper strip is passing by its wedgepiece 11, all as is plainwithout further description.

Having thus described my invention, what I claim, and desire to secureby Letters Pat- 5 cut, is-

In a mechanical musical instrument in which a perforated strip, 0, isemployed, the combination of slide-valve G with the single lever 1),arranged and connected together, and in relation to the perforated andnnperforated portions of the strip 0, substantially in the mannerdescribed, whereby the said slide-valve is both opened and closed by thesingle lever D, as set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

OLIVER H. ARNO.
